This Powered Air-Purifying Respirator (PAPR) has been designed to add even greater flexibility to Avon’s revolutionary FM53™ mask and is available as an optional extra with the ST53 and ST53SD.

The addition of the STPAPR provides the additional levels of serviceability and comfort associated with powered air while still retaining the ability to switch instantly to the positive pressure SCBA mode when required. The STPAPR achieves this by utilising a Compact Demand Valve (CDV) fitted directly into the STPAPR.

The STPAPR is NIOSH certified with industrial protection under 42 CFR 84 with the FM53 and the combination cartridge, part number 033018, for protection against chlorobenzylidene malononitrile, chloroacetophenone, ammonia, chlorine, sulfur dioxide and particulates at a high efficiency level (CS/CN/ AM/CL/SD/HE).

Note: The ST53 system utilizes the NIOSH certified FM53 APR facemask as part of the ST53 system. The FM53 APR facemask can be configured to function as an SCBA, PAPR or CCBA. NIOSH does not certify or approve respirators for multi-function, combination use. The use of the FM53 APR facemask as a means for CBRN protection with an SCBA, PAPR or CCBA has not yet been approved by NIOSH.
